我厂生产的2米~3单斗挖掘机正铲斗,由原来ZG35Mn整体浇铸改为ZGMn13型奥氏体锰钢斗前壁与用16Mn普通低合金钢板焊接的斗体对焊而成。经矿山使用1年多,尚未发现损坏情况。
The 2-m~3 single-bucket excavator bucket produced by our factory is changed from the original ZG35Mn integral casting to the ZGMn13 austenitic manganese steel bucket and welded with the 16Mn common low-alloy steel plate. After more than one year of mining, no damage was found.
